Hydrogen has gained global recognition as a crucial energy resource, holding
immense potential to offer clean, efficient, cost-effective, and environmentally
friendly energy solutions. Through water electrolysis powered by green
electricity, the production of decarbonized “green hydrogen” is achievable.
Hydrogen technology emerges as a key pathway for realizing the global objective
of “carbon neutrality.” Among various water electrolysis technologies, proton
exchange membrane water electrolysis (PEMWE) stands out as exceptionally
promising. It boasts high energy density, elevated electrolysis efficiency, and
the capacity for high output pressure, making it a frontrunner in the quest for
sustainable hydrogen production.
